Are you planning to put in a new tile or stone floor? If so, there is no better way to make it cozy and comfortable underfoot than to install a radiant floor heating system.
Of the various types of radiant floor heaters, one of the easiest to install is a fiberglass-mesh-backed matting that contains electric-resistance cables. Here we show you the basics for installing this type. The product shown is TempZone by WarmlyYours.

When ordering this system, send a floor plan of the bathroom (or other room) to WarmlyYours; the company will calculate the amount of material needed and fax or mail back to you a layout showing exactly where to cut and position the mesh for the best coverage and easiest installation.

Before beginning, discuss electrical requirements with an electrical contractor. Your system may require a dedicated circuit and will definitely require protection by a ground-fault circuit interrupter (GFCI). You'll also want the electrician to do the final hook-up (Step 4).

Please note: Observe the manufacturer's instructions implicitly. The steps that follow are meant to be a general overview of the installation sequence.

1) Simply use a pair of scissors to cut the mesh backing according to the layout. This creates rectangular panels or exposed cables that can be positioned back and forth across the floor and fitted around fixtures and cabinetry. You only cut the mesh—never the cables.
2) After using the supplied tester to make sure the cables are intact and working, apply a 1/8-inch coating of thinset cement or flooring adhesive over the top of the mesh. (You can staple or glue the mesh—but not the cables—to the subfloor to hold it in place before applying the thinset.)
3) Embed stone or floor tiles in an additional layer of thinset cement. For more about this, see Tiling a Floor.
4) Have the system wired to a thermostat that's installed in a standard 2-by-4 or 4-by-4-inch wall box by an electrician. The rounded plastic piece shown here is a tester used to ensure that the system is working.
